INTRODUCTION Recent trends in computing have shifted toward multi-core processors and programmable graphics processors with highly parallel data paths for processing geometry and pixels. Multi-core machines are now readily available with 2 cores, but machines with 4, 8, and even 16 cores are projected for the near future. Data parallelism in modern graphics(More)
In visual perception, change blindness describes the phenomenon that persons viewing a visual scene may apparently fail to detect significant changes in that scene. These phenomena have been observed in both computer generated imagery and real-world scenes. Several studies have demonstrated that change blindness effects occur primarily during visual(More)
The display units integrated in today's head-mounted displays (HMDs) provide only a limited field of view (FOV) to the virtual world. In order to present an undistorted view to the virtual environment (VE), the perspective projection used to render the VE has to be adjusted to the limitations caused by the HMD characteristics. In particular, the geometric(More)
This paper presents an approach to generating and managing ambient traac to meet situational requirements of experiments in real-time virtual driving environments. The techniques support creation of scenarios that involve prescribed action of principal role-playing vehicles taking place in a backdrop of ambient traac. Methods for initializing and(More)
